<strong>GNU Lesser General Public License<br>
Version 2.1, February 1999 </strong> 
<p>Copyright (C) 1991, 1999 Free Software Foundation, Inc.<br>
  59 Temple Place, Suite 330, Boston, MA 02111-1307 USA<br>
  Everyone is permitted to copy and distribute verbatim copies<br>
  of this license document, but changing it is not allowed.</p>
<p>[This is the first released version of the Lesser GPL. It also counts<br>
  as the successor of the GNU Library Public License, version 2, hence<br>
  the version number 2.1.]</p>
<p>Preamble<br>
  The licenses for most software are designed to take away your freedom to share 
  and change it. By contrast, the GNU General Public Licenses are intended to 
  guarantee your freedom to share and change free software--to make sure the software 
  is free for all its users. </p>
<p>This license, the Lesser General Public License, applies to some specially 
  designated software packages--typically libraries--of the Free Software Foundation 
  and other authors who decide to use it. You can use it too, but we suggest you 
  first think carefully about whether this license or the ordinary General Public 
  License is the better strategy to use in any particular case, based on the explanations 
  below. </p>
<p>When we speak of free software, we are referring to freedom of use, not price. 
  Our General Public Licenses are designed to make sure that you have the freedom 
  to distribute copies of free software (and charge for this service if you wish); 
  that you receive source code or can get it if you want it; that you can change 
  the software and use pieces of it in new free programs; and that you are informed 
  that you can do these things.</p>
<p>To protect your rights, we need to make restrictions that forbid distributors 
  to deny you these rights or to ask you to surrender these rights. These restrictions 
  translate to certain responsibilities for you if you distribute copies of the 
  library or if you modify it. </p>
<p>For example, if you distribute copies of the library, whether gratis or for 
  a fee, you must give the recipients all the rights that we gave you. You must 
  make sure that they, too, receive or can get the source code. If you link other 
  code with the library, you must provide complete object files to the recipients, 
  so that they can relink them with the library after making changes to the library 
  and recompiling it. And you must show them these terms so they know their rights. 
</p>
<p>We protect your rights with a two-step method: (1) we copyright the library, 
  and (2) we offer you this license, which gives you legal permission to copy, 
  distribute and/or modify the library. </p>
<p>To protect each distributor, we want to make it very clear that there is no 
  warranty for the free library. Also, if the library is modified by someone else 
  and passed on, the recipients should know that what they have is not the original 
  version, so that the original author's reputation will not be affected by problems 
  that might be introduced by others. </p>
<p>Finally, software patents pose a constant threat to the existence of any free 
  program. We wish to make sure that a company cannot effectively restrict the 
  users of a free program by obtaining a restrictive license from a patent holder. 
  Therefore, we insist that any patent license obtained for a version of the library 
  must be consistent with the full freedom of use specified in this license. </p>
<p>Most GNU software, including some libraries, is covered by the ordinary GNU 
  General Public License. This license, the GNU Lesser General Public License, 
  applies to certain designated libraries, and is quite different from the ordinary 
  General Public License. We use this license for certain libraries in order to 
  permit linking those libraries into non-free programs. </p>
<p>When a program is linked with a library, whether statically or using a shared 
  library, the combination of the two is legally speaking a combined work, a derivative 
  of the original library. The ordinary General Public License therefore permits 
  such linking only if the entire combination fits its criteria of freedom. The 
  Lesser General Public License permits more lax criteria for linking other code 
  with the library. </p>
<p>We call this license the &quot;Lesser&quot; General Public License because 
  it does Less to protect the user's freedom than the ordinary General Public 
  License. It also provides other free software developers Less of an advantage 
  over competing non-free programs. These disadvantages are the reason we use 
  the ordinary General Public License for many libraries. However, the Lesser 
  license provides advantages in certain special circumstances. </p>
<p>For example, on rare occasions, there may be a special need to encourage the 
  widest possible use of a certain library, so that it becomes a de-facto standard. 
  To achieve this, non-free programs must be allowed to use the library. A more 
  frequent case is that a free library does the same job as widely used non-free 
  libraries. In this case, there is little to gain by limiting the free library 
  to free software only, so we use the Lesser General Public License. </p>
<p>In other cases, permission to use a particular library in non-free programs 
  enables a greater number of people to use a large body of free software. For 
  example, permission to use the GNU C Library in non-free programs enables many 
  more people to use the whole GNU operating system, as well as its variant, the 
  GNU/Linux operating system. </p>
<p>Although the Lesser General Public License is Less protective of the users' 
  freedom, it does ensure that the user of a program that is linked with the Library 
  has the freedom and the wherewithal to run that program using a modified version 
  of the Library. </p>
<p>The precise terms and conditions for copying, distribution and modification 
  follow. Pay close attention to the difference between a &quot;work based on 
  the library&quot; and a &quot;work that uses the library&quot;. The former contains 
  code derived from the library, whereas the latter must be combined with the 
  library in order to run. </p>
<p>TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION<br>
  0. This License Agreement applies to any software library or other program which 
  contains a notice placed by the copyright holder or other authorized party saying 
  it may be distributed under the terms of this Lesser General Public License 
  (also called &quot;this License&quot;). Each licensee is addressed as &quot;you&quot;.</p>
<p>A &quot;library&quot; means a collection of software functions and/or data 
  prepared so as to be conveniently linked with application programs (which use 
  some of those functions and data) to form executables. </p>
<p>The &quot;Library&quot;, below, refers to any such software library or work 
  which has been distributed under these terms. A &quot;work based on the Library&quot; 
  means either the Library or any derivative work under copyright law: that is 
  to say, a work containing the Library or a portion of it, either verbatim or 
  with modifications and/or translated straightforwardly into another language. 
  (Hereinafter, translation is included without limitation in the term &quot;modification&quot;.) 
</p>
<p>&quot;Source code&quot; for a work means the preferred form of the work for 
  making modifications to it. For a library, complete source code means all the 
  source code for all modules it contains, plus any associated interface definition 
  files, plus the scripts used to control compilation and installation of the 
  library.</p>
<p>Activities other than copying, distribution and modification are not covered 
  by this License; they are outside its scope. The act of running a program using 
  the Library is not restricted, and output from such a program is covered only 
  if its contents constitute a work based on the Library (independent of the use 
  of the Library in a tool for writing it). Whether that is true depends on what 
  the Library does and what the program that uses the Library does. </p>
<p>1. You may copy and distribute verbatim copies of the Library's complete source 
  code as you receive it, in any medium, provided that you conspicuously and appropriately 
  publish on each copy an appropriate copyright notice and disclaimer of warranty; 
  keep intact all the notices that refer to this License and to the absence of 
  any warranty; and distribute a copy of this License along with the Library. 
</p>
<p>You may charge a fee for the physical act of transferring a copy, and you may 
  at your option offer warranty protection in exchange for a fee. </p>
<p>2. You may modify your copy or copies of the Library or any portion of it, 
  thus forming a work based on the Library, and copy and distribute such modifications 
  or work under the terms of Section 1 above, provided that you also meet all 
  of these conditions: </p>
<p>a) The modified work must itself be a software library. </p>
<p>b) You must cause the files modified to carry prominent notices stating that 
  you changed the files and the date of any change.</p>
<p>c) You must cause the whole of the work to be licensed at no charge to all 
  third parties under the terms of this License. </p>
<p>d) If a facility in the modified Library refers to a function or a table of 
  data to be supplied by an application program that uses the facility, other 
  than as an argument passed when the facility is invoked, then you must make 
  a good faith effort to ensure that, in the event an application does not supply 
  such function or table, the facility still operates, and performs whatever part 
  of its purpose remains meaningful. </p>
<p>(For example, a function in a library to compute square roots has a purpose 
  that is entirely well-defined independent of the application. Therefore, Subsection 
  2d requires that any application-supplied function or table used by this function 
  must be optional: if the application does not supply it, the square root function 
  must still compute square roots.) </p>
<p>These requirements apply to the modified work as a whole. If identifiable sections 
  of that work are not derived from the Library, and can be reasonably considered 
  independent and separate works in themselves, then this License, and its terms, 
  do not apply to those sections when you distribute them as separate works. But 
  when you distribute the same sections as part of a whole which is a work based 
  on the Library, the distribution of the whole must be on the terms of this License, 
  whose permissions for other licensees extend to the entire whole, and thus to 
  each and every part regardless of who wrote it. </p>
<p>Thus, it is not the intent of this section to claim rights or contest your 
  rights to work written entirely by you; rather, the intent is to exercise the 
  right to control the distribution of derivative or collective works based on 
  the Library. </p>
<p>In addition, mere aggregation of another work not based on the Library with 
  the Library (or with a work based on the Library) on a volume of a storage or 
  distribution medium does not bring the other work under the scope of this License. 
</p>
<p>3. You may opt to apply the terms of the ordinary GNU General Public License 
  instead of this License to a given copy of the Library. To do this, you must 
  alter all the notices that refer to this License, so that they refer to the 
  ordinary GNU General Public License, version 2, instead of to this License. 
  (If a newer version than version 2 of the ordinary GNU General Public License 
  has appeared, then you can specify that version instead if you wish.) Do not 
  make any other change in these notices. </p>
<p>Once this change is made in a given copy, it is irreversible for that copy, 
  so the ordinary GNU General Public License applies to all subsequent copies 
  and derivative works made from that copy. </p>
<p>This option is useful when you wish to copy part of the code of the Library 
  into a program that is not a library. </p>
<p>4. You may copy and distribute the Library (or a portion or derivative of it, 
  under Section 2) in object code or executable form under the terms of Sections 
  1 and 2 above provided that you accompany it with the complete corresponding 
  machine-readable source code, which must be distributed under the terms of Sections 
  1 and 2 above on a medium customarily used for software interchange. </p>
<p>If distribution of object code is made by offering access to copy from a designated 
  place, then offering equivalent access to copy the source code from the same 
  place satisfies the requirement to distribute the source code, even though third 
  parties are not compelled to copy the source along with the object code.</p>
<p>5. A program that contains no derivative of any portion of the Library, but 
  is designed to work with the Library by being compiled or linked with it, is 
  called a &quot;work that uses the Library&quot;. Such a work, in isolation, 
  is not a derivative work of the Library, and therefore falls outside the scope 
  of this License. </p>
<p>However, linking a &quot;work that uses the Library&quot; with the Library 
  creates an executable that is a derivative of the Library (because it contains 
  portions of the Library), rather than a &quot;work that uses the library&quot;. 
  The executable is therefore covered by this License. Section 6 states terms 
  for distribution of such executables. </p>
<p>When a &quot;work that uses the Library&quot; uses material from a header file 
  that is part of the Library, the object code for the work may be a derivative 
  work of the Library even though the source code is not. Whether this is true 
  is especially significant if the work can be linked without the Library, or 
  if the work is itself a library. The threshold for this to be true is not precisely 
  defined by law. </p>
<p>If such an object file uses only numerical parameters, data structure layouts 
  and accessors, and small macros and small inline functions (ten lines or less 
  in length), then the use of the object file is unrestricted, regardless of whether 
  it is legally a derivative work. (Executables containing this object code plus 
  portions of the Library will still fall under Section 6.) </p>
<p>Otherwise, if the work is a derivative of the Library, you may distribute the 
  object code for the work under the terms of Section 6. Any executables containing 
  that work also fall under Section 6, whether or not they are linked directly 
  with the Library itself. </p>
<p>6. As an exception to the Sections above, you may also combine or link a &quot;work 
  that uses the Library&quot; with the Library to produce a work containing portions 
  of the Library, and distribute that work under terms of your choice, provided 
  that the terms permit modification of the work for the customer's own use and 
  reverse engineering for debugging such modifications. </p>
<p>You must give prominent notice with each copy of the work that the Library 
  is used in it and that the Library and its use are covered by this License. 
  You must supply a copy of this License. If the work during execution displays 
  copyright notices, you must include the copyright notice for the Library among 
  them, as well as a reference directing the user to the copy of this License. 
  Also, you must do one of these things: </p>
<p>a) Accompany the work with the complete corresponding machine-readable source 
  code for the Library including whatever changes were used in the work (which 
  must be distributed under Sections 1 and 2 above); and, if the work is an executable 
  linked with the Library, with the complete machine-readable &quot;work that 
  uses the Library&quot;, as object code and/or source code, so that the user 
  can modify the Library and then relink to produce a modified executable containing 
  the modified Library. (It is understood that the user who changes the contents 
  of definitions files in the Library will not necessarily be able to recompile 
  the application to use the modified definitions.) </p>
<p>b) Use a suitable shared library mechanism for linking with the Library. A 
  suitable mechanism is one that (1) uses at run time a copy of the library already 
  present on the user's computer system, rather than copying library functions 
  into the executable, and (2) will operate properly with a modified version of 
  the library, if the user installs one, as long as the modified version is interface-compatible 
  with the version that the work was made with. </p>
<p>c) Accompany the work with a written offer, valid for at least three years, 
  to give the same user the materials specified in Subsection 6a, above, for a 
  charge no more than the cost of performing this distribution. </p>
<p>d) If distribution of the work is made by offering access to copy from a designated 
  place, offer equivalent access to copy the above specified materials from the 
  same place. </p>
<p>e) Verify that the user has already received a copy of these materials or that 
  you have already sent this user a copy.</p>
<p>For an executable, the required form of the &quot;work that uses the Library&quot; 
  must include any data and utility programs needed for reproducing the executable 
  from it. However, as a special exception, the materials to be distributed need 
  not include anything that is normally distributed (in either source or binary 
  form) with the major components (compiler, kernel, and so on) of the operating 
  system on which the executable runs, unless that component itself accompanies 
  the executable. </p>
<p>It may happen that this requirement contradicts the license restrictions of 
  other proprietary libraries that do not normally accompany the operating system. 
  Such a contradiction means you cannot use both them and the Library together 
  in an executable that you distribute. </p>
<p>7. You may place library facilities that are a work based on the Library side-by-side 
  in a single library together with other library facilities not covered by this 
  License, and distribute such a combined library, provided that the separate 
  distribution of the work based on the Library and of the other library facilities 
  is otherwise permitted, and provided that you do these two things: </p>
<p>a) Accompany the combined library with a copy of the same work based on the 
  Library, uncombined with any other library facilities. This must be distributed 
  under the terms of the Sections above. </p>
<p>b) Give prominent notice with the combined library of the fact that part of 
  it is a work based on the Library, and explaining where to find the accompanying 
  uncombined form of the same work.</p>
<p>8. You may not copy, modify, sublicense, link with, or distribute the Library 
  except as expressly provided under this License. Any attempt otherwise to copy, 
  modify, sublicense, link with, or distribute the Library is void, and will automatically 
  terminate your rights under this License. However, parties who have received 
  copies, or rights, from you under this License will not have their licenses 
  terminated so long as such parties remain in full compliance. </p>
<p>9. You are not required to accept this License, since you have not signed it. 
  However, nothing else grants you permission to modify or distribute the Library 
  or its derivative works. These actions are prohibited by law if you do not accept 
  this License. Therefore, by modifying or distributing the Library (or any work 
  based on the Library), you indicate your acceptance of this License to do so, 
  and all its terms and conditions for copying, distributing or modifying the 
  Library or works based on it. </p>
<p>10. Each time you redistribute the Library (or any work based on the Library), 
  the recipient automatically receives a license from the original licensor to 
  copy, distribute, link with or modify the Library subject to these terms and 
  conditions. You may not impose any further restrictions on the recipients' exercise 
  of the rights granted herein. You are not responsible for enforcing compliance 
  by third parties with this License. </p>
<p>11. If, as a consequence of a court judgment or allegation of patent infringement 
  or for any other reason (not limited to patent issues), conditions are imposed 
  on you (whether by court order, agreement or otherwise) that contradict the 
  conditions of this License, they do not excuse you from the conditions of this 
  License. If you cannot distribute so as to satisfy simultaneously your obligations 
  under this License and any other pertinent obligations, then as a consequence 
  you may not distribute the Library at all. For example, if a patent license 
  would not permit royalty-free redistribution of the Library by all those who 
  receive copies directly or indirectly through you, then the only way you could 
  satisfy both it and this License would be to refrain entirely from distribution 
  of the Library. </p>
<p>If any portion of this section is held invalid or unenforceable under any particular 
  circumstance, the balance of the section is intended to apply, and the section 
  as a whole is intended to apply in other circumstances. </p>
<p>It is not the purpose of this section to induce you to infringe any patents 
  or other property right claims or to contest validity of any such claims; this 
  section has the sole purpose of protecting the integrity of the free software 
  distribution system which is implemented by public license practices. Many people 
  have made generous contributions to the wide range of software distributed through 
  that system in reliance on consistent application of that system; it is up to 
  the author/donor to decide if he or she is willing to distribute software through 
  any other system and a licensee cannot impose that choice. </p>
<p>This section is intended to make thoroughly clear what is believed to be a 
  consequence of the rest of this License. </p>
<p>12. If the distribution and/or use of the Library is restricted in certain 
  countries either by patents or by copyrighted interfaces, the original copyright 
  holder who places the Library under this License may add an explicit geographical 
  distribution limitation excluding those countries, so that distribution is permitted 
  only in or among countries not thus excluded. In such case, this License incorporates 
  the limitation as if written in the body of this License. </p>
<p>13. The Free Software Foundation may publish revised and/or new versions of 
  the Lesser General Public License from time to time. Such new versions will 
  be similar in spirit to the present version, but may differ in detail to address 
  new problems or concerns.</p>
<p>Each version is given a distinguishing version number. If the Library specifies 
  a version number of this License which applies to it and &quot;any later version&quot;, 
  you have the option of following the terms and conditions either of that version 
  or of any later version published by the Free Software Foundation. If the Library 
  does not specify a license version number, you may choose any version ever published 
  by the Free Software Foundation. </p>
<p>14. If you wish to incorporate parts of the Library into other free programs 
  whose distribution conditions are incompatible with these, write to the author 
  to ask for permission. For software which is copyrighted by the Free Software 
  Foundation, write to the Free Software Foundation; we sometimes make exceptions 
  for this. Our decision will be guided by the two goals of preserving the free 
  status of all derivatives of our free software and of promoting the sharing 
  and reuse of software generally. </p>
<p>NO WARRANTY </p>
<p>15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR 
  THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE 
  STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY 
  &quot;AS IS&quot; WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, 
  INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND 
  FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE 
  OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE 
  COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. </p>
<p>16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL 
  ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE 
  THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 
  GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE 
  OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR 
  DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR 
  A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER 
  OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. <br>
